摘要

•A ratiometric electrochemical sensor was developed for BPA detection.•Ag@Fe3O4-rGO composite was synthesized via one-step solvothermal method.•Ag NPs was used to generate the internal reference signal.•The sensor exhibits a linear detection range of 0.1–10.0 µM (R2 = 0.997) with a detection limit of 0.028 μM (S/N = 3).
